  1. Great overview of these new features! I’m excited for them!

    There’s a tiny typo for String.trimEnd. The header of the section is missing the “d”: String.trimEn

  2. The article’s title is misleading. How can you refer to features that are still in proposal stages with TC39 as “ES2019 JavasScript Features”? One of them is only at Stage 1!!!

  3. Correct me if I’m mistaken, but I believe your `String.trimEnd()` example is incorrect (the sample output is trimming spaces off both sides).

  4. Yea that one, although very hotly awaited, is like a throw-in from the future, should perhaps be a bonus item at the end?
